Why, yes -- yes, I am trying to make you somewhat nauseous. Whatever gave me away?

Watching slave-ship documentaries

Dear Africans c.1700,

Hey guys, how's it going. Look, I know your businesses and governments need to import iron bars from the honkies because it's a complete pain in the ass to mine the iron deposits you have but trust me, you guys (and everyone else) will be much better off if you don't trade your neighbors for the stuff. Most of that iron's just going to be made into handcuffs and leg irons and get exported back out of your countries anyway. I think you know what I'm talking about. Slavery is for old assholes who thought it was a good idea to build walls around their cities and dig moats around their houses. You're better than that.
